I am tasked to establish journaling on a small Exchange 2010 on prem environment. I am running Exchange STD so I will be doing the entire DB. I have one single DB that is 42GB. I do not know the message volume for the 75 user mailboxes.
My intent is to create and re-point the journaling to a new Journal Mailbox based on Calendar year if possible. Log file generation for the day is about 500MB if that helps with daily volume calculation.
Is there a Best Practice for sizing needs so I can create a new LUN for the Journaling DB?
